I've got a ThinkPad Edge E420 on Windows 8. I've tried to install the video driver for my AMD HD 6630M from here:
Drivers and software - ThinkPad Edge E420, Edge E520

The problem is that CCC simply doesn't work. When I try to launch it, it doesn't do anything. I checked the task mananger for the running processes, and only once did the CCC process appear and then disappeared. Every other time it just doesn't work at all. Nothing happens at all. Any ideas of how to get round this?

P.S. I installed the Intel HD driver before trying to install this from the intel site, not from Lenovo. But I am quite sure that's no problem. However, you're free to contradict me

Thanks in advance!
